StripChart paused for some moment and resumed again

[momo2013]

Hello

I have displaying problem for strip chart. I set up x-axis as continuous mode.

I updates the data by using "PlotStripChart(DisplayHandle,Chart[idx].chartCtrl,PlotBuf[idx],2,0,0,VAL_FLOAT);".

It is not happend not always but sometimes the chart looked pause and resumed again with gaps.

If I observed it closely, the values of chart  change very slightly. But X axis label is not changing and strip chart is not shift to left to show new data.

CPU usage is looked okay. I think it happenes more often  for stable data.

Do you have any idea why this is happening?

Thank you,

Momo

 ps. I tired the multithread program and gave up for synchronizing issue.

Hi Momo,

How much data are you trying to plot to the Strip Chart?  Also, how many traces are on the chart?  Could you also let us know which version of LabWindows/CVI you are seeing this behavior in?

I know it may be difficult to convey, but feel free to include screenshots of the gaps you're seeing in the data.

Also, how many graphs are on the panel? 'Cause I see that [idx] on control ID that makes me think there are more of them. Are you updating all the strip charts at a time? Do you observe this phneomenon on all charts or on one of them only?

Yes, I have maximum 12 strip charts with 2 traces in a panel and also have a function changing scaling of y axis.

I agree that I used them too much. 

After simplifying the scaling of y axis, the behavior is much better.

My version is CVI/2013.

Thank you for reply.
